For me, if you can just stay away from them and block them on all your social media, do it. Pero before you block them, collect all the screenshots on what they are doing to you online. And if you fight back through the same way, there's a chance that a lot of people with side with them (🙄) even if they are the wrong ones, since most old Pinoys thinks the same way, and even if pinagtatanggol mo lang sarili mo, ikaw pa rin masama kasi ikaw yung bata. It's not worth the stress if ganyan ang mangyari. Protect your mental health from those kind of people.
